The gauge field becomes an essential part of the description of a mathematical configuration ... A configuration in which the gauge field can be eliminated by a gauge transformation has the property that its field strength (in mathematical language, its curvature) is zero everywhere a gauge theory is not limited ...

Famous quotes containing the word theory:

    The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.
    Thomas Henry Huxley (1825–95)
